CHARLES A. VAUGHN, OF SEITZLAND, PENNSYLVANIA.

AlR-HEATIING SYSTEM.

SPECIFICATION forming part of Letters Patent No. 757,074, dated April 12, 1904.

Application filed March 24, I903.

To all whom it may concern:

Be it known that I, CHARLES A. VAUGHN, a citizen of the United States, residing at Seitzland, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Air-Heating Systems, of which the following is a-specification, reference being had therein to the accompanying drawings.

The present invention relates to air-heating systems, and is designed to provide a small local heating system particularly adapted for use, in houses where the installation or maintenance of a larger heating plant is costly and undesirable.

The present invention provides a system of heating which may be attached to and operated from a stove or heater of an ordinary type and may be readily installed in dwellinghouses Without the necessity of materially reconstructing or rearranging the house interior to any considerable extent.

In the accompanying drawings, Figure 1 is a view, partly in section, showing the preferred form of the improved heating system. Fig. 2 is a transverse sectional view on line 2 2 of Fig. 1, to show the supporting-braces for the interior or fresh-air pipe. Fig. 3 is a detail View of the cold-air-pipednlet construction and the controlling-valve therefor.

Referring to the drawings by numerals, like numbers indicating like parts in the several views, 2 denotes the heater or stove, which may be of any desired construction and the combustion-chamber of which delivers through the outlet 3 to the interior of a heating-chamber which, as shown in Fig. 1, consists of the smoke-pipe 4. From the said heating-chamber the products of combustion may pass to any suitable flue or chimney. In this preferred form of the invention the chamber of the smoke-pipe 4 communicates with the chamber of a distributing drum or heater 5, located in an apartment above that in which the stove or heater 2 is placed, and the chamber of the said drum or heater communicates in turn with a pipe or flue 6, which may enter any suitable flue or chimney. Within the said smoke-pipe or heating-chamber 4 is located a fresh-air pipe 7 which, as herein shown, is supported Serial No. 149,240. (No model.)

at its lower end on an inlet-elbow 8. In order to control the entrance of fresh air into the said fresh-air pipe 7 a swinging valve or damper'9 is provided, the said swinging valve or damper being shown in its open position in Fig. 1 and in its closed position in Fig. 3. The upper part of the fresh-airpipe 7 is disposed in a coil 10 Within the drum or heater 5, and which coil opens at its upper end into the upper chamber or apartment, in which the said drum or heater is located.

In order to maintain and support the freshair pipe 7 in a central position within the smoke-pipe 4, semicircular strips ll,connected together and clamped to the fresh-air pipe by bolts 12 and having outturned ends to impinge against the inner wall of the smoke-pipe, are preferably provided. I

It will be observed that the invention herein shown and described comprises a stove or heater in a lower apartment and the combustion-chamber of which stove or heater communicates with a heatingchamber through which passes a cold or fresh air pipe opening through a drum or heater into an upper apartment or an apartment above that in which the stove or heater is located.

The operation of the system will be apparent from the foregoing description, and as the construction shown and described is capable of variations within the range of mechanical skill I do not wish to be understood as limiting my invention to the exact details herein shown and described.

Having thus described my invention, I claim and desire to secure by Letters Patent 1. In an air-heating system, the combination with a stove or heater, of a heating-chamher in communication with the combustionchamber of said stove or heater, a fresh-air pipe traversing said heating-chamber, and a distributor in an apartment above that in which the said stove or heater is located and from which distributer the fresh heated air is delivered into the upper apartmenhsaid distributer comprising a coil which is in com munication with the said fresh-air pipe and from which coil the heated fresh air is delivered into said upper apartment, and. a drum the chamber of which is in communication with let-elbow secured in the side of said smoke pipe to receive and support said fresh-air pipe, and semicircular strips or braces having outturned ends clamped to said fresh-air pipe and serving to center and support the same Within the smoke-pipe.

In testimony whereof I affix my signature in presence of tWo Witnesses.
